I am a chronic dislocator so I have some help for you in terms of what works for me. I have dislocated my patella on my right knee 4 times and my left twice. I started in 1998 when I was 18 and my last was May of 2003. After my last dislocation I said enough with that. I was extremely active and just couldn't say no to a pick up basketball game or any other sport for that matter but realized the way things were that it was too risky to do it again. Well around 2005 I got tired of being on the sidelines so I bought braces. One for the left and one for the right. What the previous DPT said on here was a J brace and I think that is what I have. You velcro it around your leg and there is an additional part of the brace that you then pull from the outside up and over the patella that velcros to the rest of the brace. Underneath that part that you pull up and over is a horseshoe looking pad that when pulled over the patella serves to give external support. So the good thing is that I have not dislocated since. Now I know my limits. I stay on the outside during basketball games and shoot from the perimeter. I play defense to a degree but I know to let a guy past me if I get beat laterally. I basically stay restricted to sand volleyball and softball (well, and golf). But no dislocations which is greatness.

Problem is: after you dislocate as much I have, other problems show up later. I had a partial tear in my Wikipedia reference-linkmeniscus that wasn't even noticable in activity. When the knee becomes structually unstable, other things get jacked up. Well I was wearing my brace and rounded third in the spring of 2007 when I blew out my medial and lateral meniscus. Since had surgery to trim those out, had microfracture surgery on the backside of the patella to promote resurfacing because they had to smooth the cartilage there (every time you dislocate it jacks up the cartilage as the knee cap rides up and over the groove and then back in), and did a lateral release to help the dislocation because the doc said what the heck, we are in there already.

Can't really run on pavement anymore, but I can still play softball (shortstop) and sand volleyball. The eliptical is my friend.

My advice is to take it easy. I know you are young and if you are like me just love to be active. There are bigger pictures to consider. Every time you dislocate you increase the problems you will have later in life. I am now 28 and I will tell you that later in life is already upon me Get the braces. I know some doctors will say they don't work. I can't give you guarantees, only what I have experienced in terms of no dislocations after thousands of hours of sports with them on. My braces look like the ones on this site (I can't show you this because I don't have enough posts so email me if you want a picture of what I use)

I won't ever say to not play sports but be selective. Once you dislocate you are exponentially more ept to do it again and again. The braces worked for me so there is that too. My doc also said to take glucosamine. He mentioned that all of the other stuff is junk in terms of it is not shown to actually get to the cartilage in the knee. Glucosamine does and he is a big proponent of it. He was Dallas' doctor of the year in 2004 or 5 or something and a stand up guy so I believe him. Good luck!
